Nhs checker keeps flashing up 999 help

Ok I don't need to ring 999, I'm pretty certain I have pluricy, pain for two weeks but steadily got worse in the last 24 hours just unsure wether to go to out of hours tomorrow or wait it out till Monday. Thanks

Thanks been back today, have tramadol, to add to the mix, temp high but sats not to bad so just got to rest and fight it off. I'm to go back if fever gets worse but at least the GP's open tomorrow and due to see chest consultant Tuesday. Thanks for the support
